Abstract: An optical sensor includes a substrate, a photoelectric element disposed on the substrate and that includes a first electrode, an intermediate layer disposed on the first electrode, and a second electrode disposed on the intermediate layer, a barrier layer disposed on the second electrode, an insulating layer that covers the photoelectric element and the barrier layer, and a bias electrode disposed on the insulating layer and electrically connected to the second electrode. The barrier layer is spaced apart from the first electrode.

Abstract: Disclosed herein are systems, devices, and methods related for generating a recommendation to repair an asset based on operating data. A computing system may be configured maintain a hierarchy that comprises two or more distinct levels of conditions that operating data may be checked against in order to determine which repair recommendation (if any) should be output. The hierarchy may include at least (1) a first condition that corresponds to a first repair recommendation having a first level of precision, and (2) a second condition that corresponds to a second repair recommendation having a second level of precision. Once repair recommendations are identified for satisfied conditions, the computer system may select the recommendation having the highest level of precision and then cause that recommendation to be output.
